## Customer Reviews

### ⭐⭐⭐⭐⭐ Simple Set Up, Works As Advertised.
*by A***G on June 3, 2025*

Works great in an Elitedesk G4 and an HP Prodesk 600 G3.Install was simple. Using it with a Yottamaster 5-Bay DAS with USB-C 3.1 Gen 2; speeds are really good especially since I am always transferring large amounts of data to/from my HDD's and SSD's. I can send data to 4 drives at the same time and maintain 230-250Mb/s on each.One thing to note if this get stuck at boot, a new option shows up in BIOS, I forget the location but there will be a new checkbox for USB-C firmware update for that flex I/O port. Disable it.Been using this for a while now with no issues.

### ⭐⭐⭐⭐⭐ Works well.
*by A***R on April 6, 2025*

It is great and useful and works with elitedesk 800 g5 well. I have usb c display port on it with no problem.

### ⭐⭐⭐⭐⭐ Perfect
*by J***R on February 6, 2025*

Genuine article works perfectly in a Prodesk 600 G4 Mini. They are not shown in the photo but the package includes the necessary screws, which I was worried about not having. The is so much better than having to goof around with DP and USB cables. Now I have a 1-cable solution for display, keyboard, and mouse.
